The relationship between asthma and pollution levels in Prince George, British Columbia

University of British Columbia

Three methods are used to analyse the relationships between asthma and pollution levels in Prince George. The first is the spectral analysis approach, which concentrates on the spectra of the pollusion level series and the asthma counts series, their cross spectra, their coherency, and a measure of the linear relationship between them. The other two methods are what we term the "generalized harmonic process" and the "generalized autoregressive approach", which generalize the traditional harmonic process and autoregressive model and allow us to analyse time series with less restricted distribution assumption such as discrete time series. The analyses suggests a weak positive association between asthma and the pollution levels of total reduced sulphates.
